Adaptive envelope shaping for low and medium power amplifiers with dynamic supply
(2016-07-01)
Article
Open AccessThis letter presents an adaptive envelope shaping (AES) method to linearize low and medium power amplifiers (PAs) with dynamic supply. This straightforward linearization solution results very useful for small cell or handset ... -
Constant-gain envelope tracking in a UHF outphasing transmitter based on continuousmode class-E GaN HEMT PAs
(Institute of Electrical and Electronics Engineers (IEEE), 2016)
Conference report
Restricted access - publisher's policyA UHF outphasing transmitter, based on continuous-mode class-E power amplifiers (PAs) and implementing a constant-gain envelope tracking (ET) strategy, is presented in this paper. Drain terminating and biasing networks are ... -
Digital predistorters go multidimensional: DPD for concurrent multiband envelope tracking and outphasing power amplifiers
(2019-05-01)
Article
Open AccessOver at least the last two decades, digital predistortion (DPD) has become the most common and widespread solution to cope with the power amplifier's (PA's) inherent linearity-versus-efficiency tradeoff. When compared with ... -
Digital predistortion linearization of a GaN HEMT push-pull power amplifier for cable applications with high fractional bandwidth
(2023-03-07)
Article
Open AccessThis paper presents two linearization strategies for a custom-designed wideband push-pull (PP) power amplifier (PA) for wired communication applications such as, for example, cable TV. Two digital predistortion (DPD) ...
